DETAILED DESCRIPTION

When users in social networking systems capture and generate mediacontent, the media content is presented in a gallery display format andtypically sorted chronologically based on the date and time in which themedia content was captured or generated. As the media contentaccumulates in the user computing device's storage, it becomesincreasingly difficult to access and present the stored media contentitems from the past, such as, videos and photos. It is even moredifficult to filter through thousands of media content items that havesimilar characteristics, such as similar media content items that werecaptured in subsequent months, but during a different year.

In at least one example of the present disclosure, a system is providedthat generates a timeline content collection that displays and allowseasy access to media content items that share the same type of contentand that were captured or generated during the same date and month. Thesystem generates augmentation data (e.g., an overlay icon component)that is visually overlaid on a current media content item (e.g., animage, video, or digital photograph) that the user is viewing,

Upon receiving selection of the overlay icon component, the system scansother media. content items that are stored (e.g., remotely or at thecomputing device) and locates further media content items based on mediacontent and timestamp metadata. For example, the location of furthermedia content items may include identifying these further media contentitems as having been generated within a predetermined time range of atime included in the timestamp metadata. After a match is found, thesystem generates the timeline content collection, which include thefurther media content items, and presents the timeline contentcollection in a media content interface.

In another example, the system can navigate directly to further mediacontent items, after activating the overlay icon component, as they arepresented in a gallery-style grid media content interface. The user caneasily navigate between media content being currently viewed and mediacontent previously generated or captured that match the currently viewedmedia content and its associated timestamp.

Networked Computing Environment

FIG. 1 is a block diagram showing an example messaging system 100 forexchanging data (e.g., messages and associated content) over a network.The messaging system 100 includes multiple instances of a client device102, each of which hosts a number of applications, including a messagingclient 104. Each messaging client 104 is communicatively coupled toother instances of the messaging client 104 and a messaging serversystem 108 via a network 106 (e.g., the Internet).

A messaging client 104 is able to communicate and exchange data withanother messaging client 104 and with the messaging server system 108via the network 106. The data exchanged between messaging client 104,and between a messaging client 104 and the messaging server system 108,includes functions (e.g., commands to invoke functions) as well aspayload data (e.g., text, audio, video or other multimedia data).

The messaging server system 108 provides server-side functionality viathe network 106 to a particular messaging client 104. While certainfunctions of the messaging system 100 are described herein as beingperformed by either a messaging client 104 or by the messaging serversystem 108, the location of certain functionality either within themessaging client 104 or the messaging server system 108 may be a designchoice, For example, it may be technically preferable to initiallydeploy certain technology and functionality within the messaging serversystem 108 but to later migrate this technology and functionality to themessaging client 104 where a client device 102 has sufficient processingcapacity.

The messaging server system 108 supports various services and operationsthat are provided to the messaging client 104. Such operations includetransmitting data to, receiving data from, and processing data generatedby the messaging client 104. This data may include message content,client device information, geolocation information, media augmentationand overlays, message content persistence conditions, social networkinformation, and live event information, as examples. Data exchangeswithin the messaging system 100 are invoked and controlled throughfunctions available via user interfaces (UIs) of the messaging client104.

Turning now specifically to the messaging server system 108, anApplication Program Interface (API) server 110 is coupled to, andprovides a programmatic interface to, application servers 112. Theapplication servers 112 are communicatively coupled to a database server118, which facilitates access to a database 120 that stores dataassociated with messages processed by the application servers 112.Similarly, a web server 124 is coupled to the application servers 112,and provides web-based interfaces to the application servers 112. Tothis end, the web server 124 processes incoming network requests overthe Hypertext Transfer Protocol (HTFP) and several other relatedprotocols.

The Application Program Interface (API) server 110 receives andtransmits message data (e.g., commands and message payloads) between theclient device 102 and the application servers 112. Specifically, theApplication Program Interface (API) server 110 provides a set ofinterfaces (e.g., routines and protocols) that can be called or queriedby the messaging client 104 in order to invoke functionality of theapplication servers 112. The Application Program Interface (API) server110 exposes various functions supported by the application servers 112,including account registration, login functionality, the sending ofmessages, via the application servers 112, from a particular messagingclient 104 to another messaging client 104, the sending of media files(e.g., images or video) from a messaging client 104 to a messagingserver 114, and for possible access by another messaging client 104, thesettings of a collection of media data (e.g., story), the retrieval of alist of friends of a user of a client device 102, the retrieval of suchcollections, the retrieval of messages and content, the addition anddeletion of entities (e.g., friends) to an entity graph (e.g., a socialgraph), the location of friends within a social graph, and opening anapplication event (e.g., relating to the messaging client 104).

The application servers 112 host a number of server applications andsubsystems, including for example a messaging server 114, an imageprocessing server 116, and a social network server 122. The messagingserver 114 implements a number of message processing technologies andfunctions, particularly related to the aggregation and other processingof content (e.g., textual and multimedia content) included in messagesreceived from multiple instances of the messaging client 104. As will bedescribed in further detail, the text and media content from multiplesources may be aggregated into collections of content (e.g., calledstories or galleries). These collections are then made available to themessaging client 104. Other processor and memory intensive processing ofdata may also be performed server-side by the messaging server 114, inview of the hardware requirements for such processing.

The application servers 112 also include an image processing server 116that is dedicated to performing various image processing operations,typically with respect to images or video within the payload of amessage sent from or received at the messaging server 114.

The social network server 122 supports various social networkingfunctions and services and makes these functions and services availableto the messaging server 114. To this end, the social network server 122maintains and accesses an entity graph 306 (as shown in FIG. 3) withinthe database 120. Examples of functions and services supported by thesocial network server 122 include the identification of other users ofthe messaging system 100 with which a particular user has relationshipsor is “following,” and also the identification of other entities andinterests of a particular user.

System Architecture

FIG. 2 is a block diagram illustrating further details regarding themessaging system 100, according to some examples. Specifically, themessaging system 100 is shown to comprise the messaging client 104 andthe application servers 112. The messaging system 100 embodies a numberof subsystems, which are supported on the client-side by the messagingclient 104 and on the sever-side by the application servers 112. Thesesubsystems include, for example, an ephemeral timer system 202, acollection management system 204, an augmentation system 206, a mapsystem 208, a game system 210, and a timeline content collection system212.

The ephemeral timer system 202 is responsible for enforcing thetemporary or time-limited access to content by the messaging client 104and the messaging server 114, The ephemeral timer system 202incorporates a number of timers that, based on duration and displayparameters associated with a message, or collection of messages (e.g., astory), selectively enable access (e.g., for presentation and display)to messages and associated content via the messaging client 104. Furtherdetails regarding the operation of the ephemeral timer system 202 areprovided below.

The collection management system 204 is responsible for managing sets orcollections of media (e.g., collections of text, image video, and audiodata). A collection of content (e.g., messages, including images, video,text, and audio) may be organized into an “event gallery” or an “eventstory.” Such a collection may be made available for a specified timeperiod, such as the duration of an event to which the content relates.For example, content relating to a music concert may be made availableas a “story” for the duration of that music concert. The collectionmanagement system 204 may also be responsible for publishing an iconthat provides notification of the existence of a particular collectionto the user interface of the messaging client 104.

The collection management system 204 furthermore includes a curationinterface 214 that allows a collection manager to manage and curate aparticular collection of content. For example, the curation interface214 enables an event organizer to curate a collection of contentrelating to a specific event (e.g., delete inappropriate content orredundant messages). Additionally, the collection management system 204employs machine vision (or image recognition technology) and contentrules to automatically curate a content collection. In certain examples,compensation may be paid to a user for the inclusion of user-generatedcontent into a collection. In such cases, the collection managementsystem 204 operates to automatically make payments to such users for theuse of their content.

The augmentation system 206 provides various functions that enable auser to augment (e.g., annotate or otherwise modify or edit) mediacontent associated with a message. For example, the augmentation system206 provides functions related to the generation and publishing of mediaoverlays for messages processed by the messaging system 100. Theaugmentation system 206 operatively supplies a media overlay oraugmentation (e.g., an image filter) to the messaging client 104 basedon a geolocation of the client device 102. In another example, theaugmentation system 206 operatively supplies a media overlay to themessaging client 104 based on other information, such as social networkinformation of the user of the client device 102. A media overlay mayinclude audio and visual content and visual effects. Examples of audioand visual content include pictures, texts, logos, animations, and soundeffeas. An example of a visual effect includes color overlaying. Theaudio and visual content or the visual effects can be applied to a mediacontent item (e.g., a photo) at the client device 102, example, themedia overlay may include text or image that can be overlaid on top of aphotograph taken by the client device 102. In another example, the mediaoverlay includes an identification of a location overlay (e.g., Venicebeach), a name of a live event, or a name of a merchant overlay (e.g.,Beach Coffee House). In another example, the augmentation system 206uses the geolocation of the client device 102 to identify a mediaoverlay that includes the name of a merchant at the geolocation of theclient device 102. The media overlay may include other indiciaassociated with the merchant. The media overlays may be stored in thedatabase 120 and accessed through the database server 118.

In some examples, the augmentation system 206 provides a user-basedpublication platform that enables users to select a geolocation on a mapand upload content associated with the selected geolocation. The usermay also specify circumstances under which a particular media overlayshould be offered to other users. The augmentation system 206 generatesa media overlay that includes the uploaded content and associates theuploaded content with the selected geolocation.

In other examples, the augmentation system 206 provides a merchant-basedpublication platform that enables merchants to select a particular mediaoverlay associated with a geolocation via a bidding process. Forexample, the augmentation system 206 associates the media overlay of thehighest bidding merchant with a corresponding geolocation for apredefined amount of time.

The map system 208 provides various geographic location functions, andsupports the presentation of map-based media content and messages by themessaging client 104. For example, the map system 208 enables thedisplay of user icons or avatars (e.g., stored in profile data 308) on amap to indicate a current or past location of “friends” of a user, aswell as media content (e.g., collections of messages includingphotographs and videos) generated by such friends, within the context ofa map. For example, a message posted by a user to the messaging system100 from a specific geographic location may be displayed within thecontext of a map at that particular location to “friends” of a specificuser on a map interface of the messaging client 104. A user canfurthermore share his or her location and status information (e.g.,using an appropriate status avatar) with other users of the messagingsystem 100 via the messaging client 104, with this location and statusinformation being similarly displayed within the context of a mapinterface of the messaging client 104 to selected users.

The game system 210 provides various gaming functions within the contextof the messaging client 104. The messaging client 104 provides a gameinterface providing a list of available games that can be launched by auser within the context of the messaging client 104, and played withother users of the messaging system 100. The messaging system 100further enables a particular user to invite other users to participatein the play of a specific game, by issuing invitations to such otherusers from the messaging client 104. The messaging client 104 alsosupports both the voice and text messaging (e.g., chats) within thecontext of gameplay, provides a leaderboard for the games, and alsosupports the provision of in-game rewards (e.g., coins and items).

The timeline content collection system 212 provides various operations,routines, and functions within the context of the messaging client 104and the application servers 112. The operations of the timeline contentcollection system 212 are executed at the messaging client 104 or theapplication servers 112 and include receiving, from a computing device,a first set of media content items, each media content item of the firstset of media content items comprising a first time data and a firstcontent metadata.

In some examples, the first set of media content items is received fromthe database 120 of the client device 102. The operations executed bythe timeline content collection system 212 also include generating anoverlay icon component associated with the first time data and the firstcontent metadata. The timeline content collection system 212 can be incommunication with the augmentation system 206 in order receive storedoverlays, filters, and augmentation data to generate the overlay iconcomponent.

The timeline content collection system 212 causes the overlay iconcomponent to be overlaid on top of each of the first set of mediacontent items, receives a selection of at least one of the overlay iconcomponents overlaid on top of one media content items of the first setof media content items, and determines a second set of media contentitems stored at the computing device or database 120 that each comprisea time data and a media content that matches the first time data and thefirst content metadata. Operations of the timeline content collectionsystem 212 further include generating a content collection interfacecomprising the second set of media content items.

Data Architecture

FIG. 3 is a schematic diagram illustrating data structures 300, whichmay be stored in the database 120 of the messaging server system 108,according to certain examples. While the content of the database 120 isshown to comprise a number of tables, it will be appreciated that thedata could be stored in other types of data structures (e.g., as anobject-oriented database).

The database 120 includes message data stored within a message table302. This message data includes, for any particular one message, atleast message sender data, message recipient (or receiver) data, and apayload. Further details regarding information that may be included in amessage, and included within the message data stored in the messagetable 302 is described below with reference to FIG. 4.

An entity table 304 stores entity data, and is linked (e.g.,referentially) to an entity graph 306 and profile data 308. Entities forwhich records are maintained within the entity table 304 may includeindividuals, corporate entities, organizations, objects, places, events,and so forth. Regardless of entity type, any entity regarding which themessaging server system 108 stores data may be a recognized entity. Eachentity is provided with a unique identifier, as well as an entity typeidentifier (not shown).

The entity graph 306 stores information regarding relationships andassociations between entities. Such relationships may be social,professional (e.g., work at a common corporation or organization)interested-based or activity-based, merely for example.

The profile data 308 stores multiple types of profile data about aparticular entity. The profile data 308 may be selectively used andpresented to other users of the messaging system 100, based on privacysettings specified by a particular entity. Where the entity is anindividual, the profile data 308 includes, for example, a user name,telephone number, address, settings (e.g., notification and privacysettings), as well as a user-selected avatar representation (orcollection of such avatar representations). A particular user may thenselectively include one or more of these avatar representations withinthe content of messages communicated via the messaging system 100, andon map interfaces displayed by messaging clients 104 to other users. Thecollection of avatar representations may include “status avatars,” whichpresent a graphical representation of a status or activity that the usermay select to communicate at a particular time.

Where the entity is a group, the profile data 308 for the group maysimilarly include one or more avatar representations associated with thegroup, in addition to the group name, members, and various settings(e.g., notifications) for the relevant group.

The database 120 also stores augmentation data, such as overlays orfilters, in an augmentation table 310. The augmentation data isassociated with and applied to videos (for which data is stored in avideo table 314) and images (for which data is stored in an image table316). For example, augmentation data within the augmentation table 310may be overlays in the form of augmented reality images, segments, oricons associated with each of the media content items or first time dataand the first content metadata. Additionally, the augmentation data mayinclude an animation, a three-dimensional object, a media contentoverlay, an avatar, or an image that is overlaid or superimposed overreceived media content items

filters In some examples, are overlays that are displayed as overlaid onan image or video during presentation to a recipient user. Filters maybe of various types, including user-selected filters from a set offilters presented to a sending user by the messaging client 104 when thesending user is composing a message. Other types of filters includegeolocation filters (also known as geo-filters), which may be presentedto a sending user based on geographic location. For example, geolocationfilters specific to a neighborhood or special location may be presentedwithin a user interface by the messaging client 104, based ongeolocation information determined by a Global Positioning System (GPS)unit of the client device 102.

Another type of filter is a data filter, which may be selectivelypresented to a sending user by the messaging client 104, based on otherinputs or information gathered by the client device 102 during themessage creation process. Examples of data filters include currenttemperature at a specific location, a current speed at which a sendinguser is traveling, battery life for a client device 102, or the currenttime.

Other augmentation data that may be stored within the image table 316includes augmented reality content items (e.g., corresponding toapplying Lenses or augmented reality experiences). An augmented realitycontent item may be a real-time special effect and sound that may beadded to an image or a video.

As described above, augmentation data includes augmented reality contentitems, overlays, image transformations, AR images, and similar termsrefer to modifications that may be applied to image data (e.g., videosor images). This includes real-time modifications, which modify an imageas it is captured using device sensors (e.g., one or multiple cameras)of a client device 102 and then displayed on a screen of the clientdevice 102 with the modifications. This also includes modifications tostored content, such as video clips in a gallery that may be modified.For example, in a client device 102 with access to multiple augmentedreality content items, a user can use a single video clip with multipleaugmented reality content items to see how the different augmentedreality content items will modify the stored clip. For example, multipleaugmented reality content items that apply different pseudorandommovement models can be applied to the same content by selectingdifferent augmented reality content items for the content. Similarly,real-time video capture may be used with an illustrated modification toshow how video images currently being captured by sensors of a clientdevice 102 would modify the captured data. Such data may simply bedisplayed on the screen and not stored in memory, or the contentcaptured by the device sensors may be recorded and stored in memory withor without the modifications (or both). In some systems, a previewfeature can show how different augmented reality content items will lookwithin different windows in a display at the same time. This can, forexample, enable multiple windows with different pseudorandom animationsto be viewed on a display at the same time.

Data and various systems using augmented reality content items or othersuch transform systems to modify content using this data can thusinvolve detection of objects (e.g., faces, hands, bodies, cats, dogs,surfaces, objects, etc.), tracking of such objects as they leave, enter,and move around the field of view in video frames, and the modificationor transformation of such objects as they are tracked. In variousembodiments, different methods for achieving such transformations may beused. Some examples may involve generating a three-dimensional meshmodel of the object or objects, and using transformations and animated.textures of the model within the video to achieve the transformation, Inother examples, tracking of points on an object may be used to place animage or texture (which may be two dimensional or three dimensional) atthe tracked position. In still further examples, neural network analysisof video frames may be used to place images, models, or textures incontent (e.g., images or frames of video). Augmented reality contentitems thus refer both to the images, models, and textures used to createtransformations in content, as well as to additional modeling andanalysis information needed to achieve such transformations with objectdetection, tracking, and placement.

Real-time video processing can be performed with any kind of video data(e.g., video streams, video files, etc.) saved in a memory of acomputerized system of any kind. For example, a user can load videofiles and save them in a memory of a device, or can generate a videostream using sensors of the device. Additionally, any objects can beprocessed using a computer animation model, such as a human's face andparts of a human body, animals, or non-living things such as chairs,cars, or other objects.

In some examples, when a particular modification is selected along withcontent to be transformed, elements to be transformed are identified bythe computing device, and then detected and tracked if they are presentin the frames of the video. The elements of the object are modifiedaccording to the request for modification, thus transforming the framesof the video stream. Transformation of frames of a video stream can beperformed by different methods for different kinds of transformation.For example, for transformations of frames mostly referring to changingforms of object's elements characteristic points for each element of anobject are calculated using an Active Shape Model (ASM) or other knownmethods). Then, a mesh based on the characteristic points is generatedfor each of the at least one element of the object. This mesh used inthe following stage of tracking the elements of the object in the videostream, In the process of tracking, the mentioned mesh for each elementis aligned with a position of each element. Then, additional points aregenerated on the mesh. A first set of first points is generated for eachelement based on a request for modification, and a set of second pointsis generated for each element based on the set of first points and therequest for modification. Then, the frames of the video stream can betransformed by modifying the elements of the object on the basis of thesets of first and second points and the mesh. In such method, abackground of the modified object can be changed or distorted as well bytracking and modifying the background.

in some examples, transformations changing some areas of an object usingits elements can be performed by calculating characteristic points foreach element of an object: and generating a mesh based on the calculatedcharacteristic points. Points are generated on the mesh, and thenvarious areas based on the points are generated. The elements of theobject are then tracked by aligning the area for each element with aposition for each of the at least one element, and properties of theareas can be modified based on the request for modification, thustransforming the frames of the video stream. Depending on the specificrequest for modification properties of the mentioned areas can betransformed in different ways. Such modifications may involve changingcolor of areas; removing at least sonic part of areas from the frames ofthe video stream; including one or more new objects into areas which arebased on a request for modification; and modifying or distorting theelements of an area or object. In various embodiments, any combinationof such modifications or other similar modifications may be used. Forcertain models to be animated, some characteristic points can beselected as control points to be used in determining the entirestate-space of options for the model animation.

In some examples of a computer animation model to transform image datausing face detection, the face is detected on an image with use of aspecific face detection algorithm (e.g., Viola-Jones). Then, an ActiveShape Model (ASM) algorithm is applied to the face region of an image todetect facial feature reference points.

In other examples, other methods and algorithms suitable for facedetection can be used. For example, in some embodiments, features arelocated using a landmark, which represents a distinguishable pointpresent in most of the images under consideration. For facial landmarks,for example, the location of the left eye pupil may be used. If aninitial landmark is not identifiable (e.g., if a person has aneyepatch), secondary landmarks may be used. Such landmark identificationprocedures may be used for any such objects. In some examples, a set oflandmarks forms a shape. Shapes can be represented as vectors using thecoordinates of the points in the shape. One shape is aligned to anotherwith a similarity transform (allowing translation, scaling, androtation) that minimizes the average Euclidean distance between shapepoints. The mean shape is the mean of the aligned training shapes.

In some examples, a search for landmarks from the mean shape aligned tothe position and size of the face determined by a global face detectoris started. Such a search then repeats the steps of suggesting atentative shape by adjusting the locations of shape points by templatematching of the image texture around each point and then conforming thetentative shape to a global shape model until convergence occurs. Insome systems, individual template matches are unreliable, and the shapemodel pools the results of the weak template matches to form a strongeroverall classifier. The entire search is repeated at each level in animage pyramid, from coarse to fine resolution.

A transformation system can capture an image or video stream on a clientdevice (e.g., the client device 102) and perform complex imagemanipulations locally on the client device 102 while maintaining asuitable user experience, computation time, and power consumption. Thecomplex image manipulations may include size and shape changes, emotiontransfers (e.g., changing a face from a frown to a smile), statetransfers (e.g., aging a subject, reducing apparent age, changinggender), style transfers, graphical element application, and any othersuitable image or video manipulation implemented by a convolutionalneural network that has been configured to execute efficiently on theclient device 102.

In some examples, a computer animation model to transform image data canbe used by a system where a user may capture an image or video stream ofthe user (e.g., a seine) using a client device 102 having a neuralnetwork operating as part of a messaging client application 104operating on the client device 102. The transformation system operatingwithin the messaging client 104 determines the presence of a face withinthe image or video stream and provides modification icons associatedwith a computer animation model to transform image data, or the computeranimation model can be present as associated with an interface describedherein. The modification icons include changes that may be the basis formodifying the user's face within the image or video stream as part ofthe modification operation. Once a modification icon is selected, thetransform system initiates a process to convert the image of the user toreflect the selected modification icon (e.g., generate a smiling face onthe user). A modified image or video stream may be presented in agraphical user interface displayed on the client device 102 as soon asthe image or video stream is captured, and a specified modification isselected. The transformation system may implement a complexconvolutional neural network on a portion of the image or video streamto generate and apply the selected modification. That is, the user maycapture the image or video stream and be presented with a modifiedresult in real-time or near real-time once a modification icon has beenselected. Further, the modification may be persistent while the videostream is being captured, and the selected modification icon remainstoggled. Machine taught neural networks may be used to enable suchmodifications.

The graphical user interface, presenting the modification performed bythe transform system, may supply the user with additional interactionoptions. Such options may be based on the interface used to initiate thecontent capture and selection of a particular computer animation model(e.g., initiation from a content creator user interface). In variousembodiments, a modification may be persistent after an initial selectionof a modification icon. The user may toggle the modification on or offby tapping or otherwise selecting the face being modified by thetransformation system and store it for later viewing or browse to otherareas of the imaging application. Where multiple faces are modified bythe transformation system, the user may toggle the modification on oroff globally by tapping or selecting a single face modified anddisplayed within a graphical user interface. In some embodiments,individual faces, among a group of multiple faces, may be individuallymodified, or such modifications may be individually toggled by tappingor selecting the individual face or a series of individual facesdisplayed within the graphical user interface.

A story table 312 stores data regarding collections of messages andassociated image, video, or audio data, which are compiled into acollection (e.g., a story or a gallery). The creation of a particularcollection may be initiated by a particular user (e.g., each user forwhich a record is maintained in the entity table 304). A user may createa “personal story” in the form of a collection of content that has beencreated and sent/broadcast by that user. To this end, the user interfaceof the messaging client 104 may include an icon that is user-selectableto enable a sending user to add specific content to his or her personalstory.

A collection may also constitute a “live story,” which is a collectionof content from multiple users that is created manually, automatically,or using a combination of manual and automatic techniques. For example,a “live story” may constitute a curated stream of user-submitted contentfrom varies locations and events. Users whose client devices havelocation services enabled and are at a common location event at aparticular time may, for example, be presented with an option, via auser interface of the messaging client 104, to contribute content to aparticular live story. The live story may be identified to the user bythe messaging client 104, based on his or her location. The end resultis a “live story” told from a community perspective.

A further type of content collection is known as a “location story,”which enables a user whose client device 102 is located within aspecific geographic location (e.g., on a college or university campus)to contribute to a particular collection. In some examples, acontribution to a location story may require a second degree ofauthentication to verify that the end user belongs to a specificorganization or other entity (e.g., is a student on the universitycampus).

As mentioned above, the video table 314 stores video data that, in someexamples, is associated with messages for which records are maintainedwithin the message table 302. Similarly, the image table 316 storesimage data associated with messages for which message data is stored inthe entity table 304. The entity table 304 may associate variousaugmentations from the augmentation table 310 with various images andvideos stored in the image table 316 and the video table 314.

Data Communications Architecture

FIG. 4 is a schematic diagram illustrating a structure of a message 400,according to some examples, generated by a messaging client 104 forcommunication to a further messaging client 104 or the messaging server114. The content of a particular message 400 is used to populate themessage table 302 stored within the database 120, accessible by themessaging server 114. Similarly, the content of a message 400 is storedin memory as “in-transit” or “in-flight” data of the client device 102or the application servers 112. A message 400 is shown to include thefollowing example components:

-   -   message identifier 402: a unique identifier that identifies the        message 400.    -   message text payload 404: text, to be generated by a user via a        user interface of the client device 102, and that is included in        the message 400.    -   message image payload 406: image data, captured by a camera        component of a client device 102 or retrieved from a memory        component of a client device 102, and that is included in the        message 400. Image data for a sent or received message 400 may        be stored in the image table 316.    -   message video payload 408: video data, captured by a camera        component or retrieved from a memory component of the client        device 102, and that is included in the message 400. Video data        for a sent or received message 400 may be stored in the video        table 314.    -   message audio payload 410: audio data, captured by a microphone        or retrieved from a memory component of the client device 102,        and that is included in the message 400.    -   message augmentation data 412: augmentation data (e.g., filters,        stickers, or other annotations or enhancements) that represents        augmentations to be applied to message image payload 406,        message video payload 408, or message audio payload 410 of the        message 400. Augmentation data for a sent or received message        400 may be stored in the augmentation table 310.    -   message duration parameter 414: parameter value indicating, in        seconds, the amount of time for which content of the message        (e.g., the message image payload 406, message video payload 408,        message audio payload 410) is to be presented or made accessible        to a user via the messaging client 104.    -   message geolocation parameter 416: geolocation data (e.g.,        latitudinal and longitudinal coordinates) associated with the        content payload of the message. Multiple message geolocation        parameter 416 values may be included in the payload, each of        these parameter values being associated with respect to content        items included in the content (e.g., a specific image into        within the message image payload 406, or a specific video in the        message video payload 408).    -   message story identifier 418: identifier values identifying one        or more content collections (e.g., “stories” identified in the        story table 312) with which a particular content item in the        message image payload 406 of the message 400 is associated. For        example, multiple images within the message image payload 406        may each be associated with multiple content collections using        identifier values.    -   message tag 420: each message 400 may be tagged with multiple        tags, each of which is indicative of the subject matter of        content included in the message payload. For example, where a        particular image included in the message image payload 406        depicts an animal (e.g., a lion), a tag value may be included        within the message tag 420 that is indicative of the relevant        animal. Tag values may be generated manually, based on user        input, or may be automatically generated using, for example,        image recognition.    -   message sender identifier 422: an identifier (e.g., a messaging        system identifier, email address, or device identifier)        indicative of a user of the Client device 102 on which the        message 400 was generated and from which the message 400 was        sent.    -   message receiver identifier 424: an identifier (e.g., a        messaging system identifier, email address, or device        identifier) indicative of a user of the client device 102 to        which the message 400 is addressed.

The contents (e.g., values) of the various components of message 400 maybe pointers to locations in tables within which content data values arestored. For example, an image value in the message image payload 406 maybe a pointer to (or address of) a location within an image table 316.Similarly, values within the message video payload 408 may point to datastored within a video table 314, values stored within the messageaugmentations 412 may point to data stored in an augmentation table 310,values stored within the message story identifier 418 may point to datastored in a story table 312, and values stored within the message senderidentifier 422 and the message receiver identifier 424 may point to userrecords stored within an entity table 304.

Times-Based Access Limitation Architecture

FIG. 5 is a schematic diagram illustrating an access-limiting process500, in terms of which access to content (e.g., an ephemeral message502, and associated multimedia payload of data) or a content collection(e.g., an ephemeral message group 504) may be time-limited (e.g., madeephemeral).

An ephemeral message 502 is shown to be associated with a messageduration parameter 506, the value of which determines an amount of timethat the ephemeral message 502 will be displayed to a receiving user ofthe ephemeral message 502 by the messaging client 104. In some examples,an ephemeral message 502 is viewable by a receiving user for up to amaximum of 10 seconds, depending on the amount of time that the sendinguser specifies using the message duration parameter 506.

The message duration parameter 506 and the message receiver identifier424 are shown to be inputs to a message timer 512, which is responsiblefor determining the amount of time that the ephemeral message 502 isshown to a particular receiving user identified by the message receiveridentifier 424. In particular, the ephemeral message 502 will only beshown to the relevant receiving user for a time period determined by thevalue of the message duration parameter 506. The message timer 512 isshown to provide output to a more generalized ephemeral timer system202, which is responsible for the overall timing of display of content(e.g., an ephemeral message 502) to a receiving user.

The ephemeral message 502 is shown in FIG. 5 to be included within anephemeral message group 504 (e.g., a collection of messages in apersonal story, or an event story). The ephemeral message group 504 hasan associated group duration parameter 508, a value of which determinesa time duration for which the ephemeral message group 504 is presentedand accessible to users of the messaging system 100. The group durationparameter 508, for example, may be the duration of a music concert,where the ephemeral message group 504 is a collection of contentpertaining to that concert. Alternatively, a user either the owning useror a. curator user) may specify the value for the group durationparameter 508 when performing the setup and creation of the ephemeralmessage group 504.

Additionally, each ephemeral message 502 within the ephemeral messagegroup 504 has an associated group participation parameter 510, a valueof which determines the duration of time for which the ephemeral message502 will be accessible within the context of the ephemeral message group504. Accordingly, a particular ephemeral message group 504 may “expire”and become inaccessible within the context of the ephemeral messagegroup 504, prior to the ephemeral message group 504 itself expiring interms of the group duration parameter 508. The group duration parameter508, group participation parameter 510, and message receiver identifier424 each provide input to a group timer 514, which operationallydetermines, firstly, whether a particular ephemeral message 502 of theephemeral message group 504 will be displayed to a particular receivinguser and, if so, for how long. Note that the ephemeral message group 504is also aware of the identity of the particular receiving user as aresult of the message receiver identifier 424.

Accordingly, the group timer 514 operationally controls the overalllifespan of an associated ephemeral message group 504, as well as anindividual ephemeral message 502 included in the ephemeral message group504. In some examples, each and every ephemeral message 502 within theephemeral message group 504 remains viewable and accessible for a timeperiod specified by the group duration parameter 508. In a furtherexample, a certain ephemeral message 502 may expire, within the contextof ephemeral message group 504, based on a group participation parameter510. Note that a message duration parameter 506 may still determine theduration of time for which a particular ephemeral message 502 isdisplayed to a receiving user, even within the context of the ephemeralmessage group 504. Accordingly, the message duration parameter 506determines the duration of time that a particular ephemeral message 502is displayed to a receiving user, regardless of whether the receivinguser is viewing that ephemeral message 502 inside or outside the contextof an ephemeral message group 504.

The ephemeral timer system 202 may furthermore operationally remove aparticular ephemeral message 502 from the ephemeral message group 504based on a determination that it has exceeded an associated groupparticipation parameter 510. For example, when a sending user hasestablished a group participation parameter 510 of 24 hours fromposting, the ephemeral timer system 202 will remove the relevantephemeral message 502 from the ephemeral message group 504 after thespecified 24 hours. The ephemeral timer system 202 also operates toremove an ephemeral message group 504 when either the groupparticipation parameter 510 for each and every ephemeral message 502within the ephemeral message group 504 has expired, or when theephemeral message group 504 itself has expired in terms of the groupduration parameter 508.

In certain use cases, a creator of a particular ephemeral message group504 may specify an indefinite group duration parameter 508. In thiscase, the expiration of the group participation parameter 510 for thelast remaining ephemeral message 502 within the ephemeral message group504 will determine when the ephemeral message group 504 itself expires.In this case, a new ephemeral message 502, added to the ephemeralmessage group 504, with a new group participation parameter 510,effectively extends the life of an ephemeral message group 504 to equalthe value of the group participation parameter 510.

Responsive to the ephemeral timer system 202 determining that anephemeral message group 504 has expired (e.g., is no longer accessible),the ephemeral timer system 202 communicates with the messaging system100 (and, for example, specifically the messaging client 104) to causean indicium (e.g., an icon) associated with the relevant ephemeralmessage group 504 to no longer be displayed within a user interface ofthe messaging client 104. Similarly, when the ephemeral timer system 202determines that the message duration parameter 506 for a particularephemeral message 502 has expired, the ephemeral timer system 202 causesthe messaging client 104 to no longer display an indicium (e.g., an iconor textual identification) associated with the ephemeral message 502.

FIG. 6 illustrates a flowchart illustrating a process 600 for generatinga timeline content collection in accordance with some embodiments. Inoperation 602, a first computing device (e.g., client device 102 orserver-side computing device) receives a first set of media contentitems, each media content item of the first set of media content itemshaving first time data (e.g., a timestamp) and first content metadata.

In some examples, each individual media content item within the firstset of media content items, contain at least one time data and one firstcontent metadata. The first set of media content is ephemeral (e.g., asa limited accessibility time window), and can include video, images,augmented reality (AR) image transformations, augmented reality contentitems. AR media content items, or three-dimensional objects.

In another example, the first set of media content items can be anon-ephemeral content, such as video, image, photograph, AR image, ARtransformation, or digital object.

The first time data is based on the capture time of the media contentitem or the time in which the media content item is stored at thecomputing device. The first time data also includes at least one ofmonth information, date information, year information, or locationinformation. The month information is based on the 12-month calendar,which includes lunar months January through December, the dateinformation includes the numerical date associated with the monthinformation, such as the 10th day of the month, e.g. January 10, and theyear information corresponds to the year in which the media content itemwas captured, stored, or generated by the computing device.

The first time data may also include a date range based on the creationdate of media content items or a day, month, and year metric measuredfrom the online social network system account generation period. Thefirst time data can also be based on a creation date associated witheach of the set of media content items being generated by the firstcomputing device.

The first content metadata records characteristics of a type of content(e.g., media content characteristics) under which each of the mediacontent items may be categorized. In another example, these mediacontent characteristics include characteristics, features, attributes,or descriptive components within each of the media content items. Forexample, the media content metadata may indicate types of eventrepresented or captured in the corresponding media content item, such assporting events, outdoor activities, indoor activities, concerts, schoolevents, church events, civic events, family events, and also the numberof people included in the media content item,

The media content characteristics are determined based on the locationat which the media content item was captured, the metadata associatedwith the media content item, the time of day in which the media contentitem was captured, the amount of objects, including people, are includedin the media content item, or media content item information associatedwith the captured or generated content as designated by the user of thecomputing device,

In operation 604, the computing device generates augmentation data inthe form of an overlay icon component associated with the first timedata and the first content metadata. The overlay icon component is anobject, image, animation, three-dimensional object, digital picture,emoji, augmented reality image, augmented reality transformation ordigital character icon.

In another example, the overlay icon component is a media contentoverlay or an avatar. The computing device retrieves augmentation data,such as overlays or filters, from the augmentation table 310 in order togenerate the overlay icon component. The augmentation data is associatedwith and applied to videos (for which data is stored in a video table314) and images (for which data is stored in an image table 316), andupon generation of the overlay icon component, the operation 606, thecomputing device causes the overlay icon component to be overlaid on topof each of the first set of media content items.

In operation 608, the computing device receives a selection of one ormore of the overlay icon components that are displayed overlaid on mediacontent items of the first set of media content items. The selection isinitiated upon a user activating a computing device (e.g., the userclient device 102) by applying a user gesture, such as pressing theoverlay icon component. In another example, a user of the computingdevice initiates contact with the overlay icon component, thusactivating the overlay icon component overlaid on top of the mediacontent items at the computing device e.g., client device).

In response to the selection of the overlay icon component, in operation610, the computing device determines a second set of media content itemsstored at the computing device (e.g., client device 102, or third-partyserver) that each comprise a time data and a content metadata thatmatches the first time data and the first content metadata. The secondset of media content items can be stored at database 120 or athird-party server.

In some examples, the computing device scans and identifies metadata andother characteristics (discussed above) associated with the firstcontent metadata and first time data and compares the identifiedmetadata and other characteristics with media content and time data.that is associated with the media content during a predetermined timeperiod. The predetermined time period can be set by the user ordetermined by the computing device (e.g., 7 days ago, 1 year ago, or 5years ago, etc.). In some examples, the predetermined time period is amonth range, a date range, or a year range calculated from the creationdate of the media content items.

For example, assume the user is actively viewing a digital photograph offive friends at Miami beach generated on May 8, 2000. The first contentmetadata identifies the associated digital photograph (as an example ofa media content item) as depicting friends at the beach. This contentmetadata may be generated using image recognition technology thatincludes artificial intelligence. Further, in the associated digitalphotograph, time data indicates the date of May 8, 2000. As the usertaps on an overlay icon component displayed overlaid on top of thedigital photograph, the computing device compares and locates anotherset of digital photographs that are stored in the database (locally orremotely) with matching date information and media content information,such as May 8 and five or more friends at Miami Beach or any type ofbeach. The computing device, in some examples, does not require an exactdate and/or time the match, but may search for other digital photographswithin a time range of a specific date, such as a week before or afterthe date of May 8, 2000.

In operation 612, the computing device generates a timeline contentcollection comprising the second set of media content items. Thetimeline content collection maybe two or more media content itemsaggregated into a group, subgroup, or subset, each of which match thefirst time data and first content metadata associated with the firstcontent metadata item. The timeline content collection is presented in agallery style format and be arranged in a polygonal array, circulararray, or interactive media content item arrangement.

In furtherance to the example above, after the computing device comparesand locates another set of digital photographs that are stored in thedatabase on May 8 and include five or more friends at Miami Beach or anytype of beach, the digital photographs that match May 8 and includefriends (any number at 5 or reasonably close to 5) at the beach, thecomputing device aggregates the matching photographs into a timelinecontent collection and presents them to the user. In operation 614, thecomputing device causes a media content collection interface to bedisplayed by the first computing device, the media content collectioninterface comprising the timeline content collection.

In another example, the computing device generates an ephemeral contentcollection timeline interface comprising the second set of media contentitems that match month information and date information associated withthe first time data. The set of media content items displayed in theephemeral content collection timeline interface are ephemeral mediacontent items.

For example, the set of media content items correspond to the ephemeralmessage group 504 (e.g., a collection of messages in a personal story,or an event story) that has an associated group duration parameter 508,a value of which determines a time duration for which the ephemeralmessage group 504 is presented and accessible to users of the messagingsystem 100. The group duration parameter 508, for example, may be theduration of an NBA basketball game, where the ephemeral message group504 is a collection of media content items pertaining to that sportingevent, such as pictures with an NBA basketball player, Alternatively, auser (either the owning user or a curator user) may specify the valuefor the group duration parameter 508 when performing the setup andcreation of the ephemeral message group 504.

FIG. 7 illustrates an example user interface 700 of a timeline contentcollection in accordance with one embodiment. The user interface 700,also referred to as the media content collection interface 700, depictsthe timeline content collection after the operations in the method 600described with reference to FIG. 6 have been executed. The media contentcollection interface 700 is generated at the first computing device andincludes the timeline content collection 714.

As shown in FIG. 7, the media content collection interface 700 alsoincludes a search field 702, a title caption 704, a first time data 706,first content metadata 720, an overlay icon component 71$, a mediacontent item 712, a second overlay icon component 710, an overlay saveicon 708, an overlay edit icon 716, a time data 722, a media content724, and the timeline content collection 714.

In some examples, the media content item 712 is one of the media contentitems received by the computing device. Although one media content mediacontent item 712 is illustrated in FIG. 7, two or more media contentitems can also be included. In one example the first time data 706associated with the media content item 712 is depicted as “Aug. 25,2019” in which the month information is “August,” the date informationis “25,” and the year information is “2019.” In another example, themedia content item 712 is associated with a 0 current time period basedon the day in which the user accesses the computing device or based on atime period manually set by the user of the computing device.

Still referring to FIG. 7, the first content metadata 720 includes themedia content characteristics shown in the media content item 712. Asdescribed above, the media content characteristics includecharacteristics, features, attributes, or descriptive components withineach of the media content items, such as, sporting events, outdooractivities, indoor activities, concerts, school events, church events,civic events, family events, the number of people included in the mediacontent item, or the like.

The media content characteristics are determined based on the locationin which the media content item was captured, the metadata associatedwith the media content item, the time of day in which the media contentitem was captured, the amount of objects and individuals that areincluded in the media content item, or media content item informationassociated with the captured or generated content as designated by theuser of the computing device.

As shown in FIG. 7, the media content characteristics include threewomen holding hands at a sporting event. As the user activates theoverlay icon component 718, which is associated with the first time data706 and the first content metadata 720, the timeline content collection714 is generated, which includes the second set of media content items726 that each comprise an associated time data 722 and content metadata724 that each match the first time data 706 and the first contentmetadata 720 associated with the media content item 712. Although theoverlay icon component 718 is depicted as a chevron icon, any animation,a three-dimensional object, media content overlay, avatar, or an imagethat is overlaid or superimposed over a set of received media contentitems can be used as the overlay icon component 718.

Further, each of the second set of media content items 726 in thetimeline content collection 714 include a time data 722 (not shown), asecond overlay icon component 710 and a media content 724 that directlymatch or closely match the media content characteristics included in themedia content item 712. In the example interface, the time data 722 isdepicted above the timeline content collection informing the user of thecomputing device that each of the second set of media content items 726include the time data 722. Although the second overlay icon component710 is depicted as a circular icon, any animation, a three-dimensionalobject, media content overlay, avatar, or an image that is overlaid orsuperimposed over a set of received media content items can be used asthe second overlay icon component 710.

For instance, media content item 726 includes a woman located at thesame sporting event one the same date in which the media content item712 was captured at the time data 722. In another example, as the useractivates the overlay icon component 718, which is associated with thefirst time data 706 and the first content metadata 720, the user isnavigated to the second set of media content items 726 individually asthey are presented and displayed in a gallery-style media contentinterface or media content grid format interface. In another example,the second overlay icon component 710 is used to generate anothertimeline content collection based on a time data and content metadataassociated with that particular media content item with the secondoverlay icon component 710.

The overlay save icon 708 and overlay edit icon 716 are overlaid on topof the media content item 712. In some examples, the overlay save icon804 stores the timeline content collection 714 at one of the storagetables in database 120. The timeline content collection 714 is storedafter a user of the computing device activates the overlay save icon 708by applying a user gesture on the overlay save icon 708. In anotherexample, the overlay edit icon 716 executes a modification function onthe timeline content collection 714 upon a user of the computing deviceapplying a user gesture on the overlay edit icon 716.

In some examples, a user can input a search query into the search field702 corresponds to a descriptive alpha-numeric character, digital image,image overlay, digital expression image, or the like relating to storedmedia content items or the second set of media content items 726. Thetitle caption 704 is overlaid on top of the media content item 712 andstates, “1 Year Ago Today”. The title caption 704 includes a textualcaption, textual alpha-numeric string of characters, digital image,image overlay, digital expression image, or the like describing themedia content item 712, associated first time data 706 or first contentmetadata 720 which can include any related string of informative titles,such as “Your First 30 days”, “Your last Month” or “Your ChristmasVacation.”

FIG. 8 illustrates an example user interface 800 of the extendedtimeline content collection in accordance with one embodiment. As shownin FIG. 8, the timeline content collection 714 is extended to show theremaining second set of media content items 726, each of which containsa second overlay icon component 710. Also depicted is a third overlayicon component 802 that navigates the user viewing the timeline contentcollection 714 back to the initial timeline content collection 714illustrated in FIG. 7.

In another example, the third overlay icon component 802 is depicted asa upward facing chevron, however, any animation, a three-dimensionalobject, media content overlay, avatar, or an image can be used. In someexamples, each of the second set of media content items 726 include thefirst time data 706 (not shown) and first content metadata 720 thatdirectly match or closely match the media content characteristicsincluded in the media content item 712.

Machine Architecture

FIG. 9 is a diagrammatic representation of the machine 900 within whichinstructions 908 (e.g., software, a program, an application, an applet,an app, or other executable code) for causing the machine 900 to performany one or more of the methodologies discussed herein may be executed.For example, the instructions 908 may cause the machine 900 to executeany one or more of the methods described herein. The instructions 908transform the general, non-programmed machine 900 into a particularmachine 900 programmed to carry out the described and illustratedfunctions in the manner described. The machine 900 may operate as astandalone device or may be coupled (e.g., networked) to other machines.In a networked deployment, the machine 900 may operate in the capacityof a server machine or a client machine in a server-client networkenvironment, or as a peer machine in a peer-to-peer (or distributed)network environment.

The machine 900 may comprise, but not be limited to, a server computer,a client computer, a personal computer (PC), a tablet computer, a laptopcomputer, a netbook, a set-top box (STB), a personal digital assistant(PDA), an entertainment media system, a cellular telephone, asmartphone, a mobile device, a wearable device (e.g., a smartwatch), asmart home device (e.g., a smart appliance), other smart devices, a webappliance, a network router, a network switch, a network bridge, or anymachine capable of executing the instructions 908, sequentially orotherwise, that specify actions to be taken by the machine 900. Further,while only a single machine 900 is illustrated, the term “machine” shallalso be taken to include a. collection of machines that individually orjointly execute the instructions 908 to perform any one or more of themethodologies discussed herein.

The machine 900, for example, may comprise the client device 102 or anyone of a number of server devices forming part of the messaging serversystem 108. In some examples, the machine 900 may also comprise bothclient and server systems, with certain operations of a particularmethod or algorithm being performed on the server-side and with certainoperations of the particular method or algorithm being performed on theclient-side.

The machine 900 may include processors 902., memory 904, andinput/output I/O components 638, which may be configured to communicatewith each other via a bus 940.

Glossary

“Carrier signal” refers to any intangible medium that is capable ofstoring, encoding, or carrying instructions for execution by themachine, and includes digital or analog communications signals or otherintangible media to facilitate communication of such instructions.Instructions may be transmitted or received over a network using atransmission medium via a network interface device.

“Client device” refers to any machine that interfaces to acommunications network to obtain resources from one or more serversystems or other client devices. A client device may be, but is notlimited to, a mobile phone, desktop computer, laptop, portable digitalassistants (PDAs), smartphones, tablets, ultrabooks, netbooks, laptops,multi-processor systems, microprocessor-based or programmable consumerelectronics, game consoles, set-top boxes, or any other communicationdevice that a user may use to access a network.

“Communication network” refers to one or more portions of a network thatmay be an ad hoc network, an intranet, an extranet, a virtual privatenetwork (VPN), a local area network (LAN), a wireless LAN ('ULAN), awide area network (WAN), a wireless WAN (WWAN), a metropolitan areanetwork (MAN), the Internet, a portion of the Internet, a portion of thePublic Switched Telephone Network (PSTN), a plain old telephone service(POTS) network, a cellular telephone network, a wireless network, aWi-Fi® network, another type of network, or a combination of two or moresuch networks. For example, a network or a portion of a network mayinclude a wireless or cellular network and the coupling may be a CodeDivision Multiple Access (CDMA) connection, a Global System for Mobilecommunications (GSM) connection, or other types of cellular or wirelesscoupling. In this example, the coupling may implement any of a varietyof types of data transfer technology, such as Single Carrier RadioTransmission Technology (1×RTT), Evolution-Data Optimized (EVDO)technology, General Packet Radio Service (GPRS) technology, EnhancedData rates for GSM Evolution (EDGE) technology, third. GenerationPartnership Project (3GPP) including 3G, fourth generation wireless (4G)networks, Universal Mobile Telecommunications System (UMTS), High SpeedPacket Access (HSPA), Worldwide Interoperability for Microwave Access(WiMAX), Long Term Evolution (LTE) standard, others defined by variousstandard-setting organizations, other long-range protocols, or otherdata transfer technology.

“Component” refers to a device, physical entity, or logic havingboundaries defined by function or subroutine calls, branch points, APIs,or other technologies that provide for the partitioning ormodularization of particular processing or control functions. Componentsmay be combined via their interfaces with other components to carry outa machine process. A component may be a packaged functional hardwareunit designed for use with other components and a part of a program thatusually performs a particular function of related functions. Componentsmay constitute either software components (e.g., code embodied on amachine-readable medium) or hardware components. A “hardware component”is a tangible unit capable of performing certain operations and may beconfigured or arranged in a certain physical manner. In various exampleembodiments, one or more computer systems (e.g., a standalone computersystem, a client computer system, or a server computer system) or one ormore hardware components of a computer system (e.g., a processor or agroup of processors) may be configured by software (e.g., an applicationor application portion) as a hardware component that operates to performcertain operations as described herein. A hardware component may also beimplemented mechanically, electronically, or any suitable combinationthereof. For example, a hardware component may include dedicatedcircuitry or logic that is permanently configured to perform certainoperations. A hardware component may be a special-purpose processor,such as a field-programmable gate array (FPGA) or an applicationspecific integrated circuit (ASIC). A hardware component may alsoinclude programmable logic or circuitry that is temporarily configuredby software to perform certain operations. For example, a hardwarecomponent may include software executed by a general-purpose processoror other programmable processor. Once configured by such software,hardware components become specific machines (or specific components ofa machine) uniquely tailored to perform the configured functions and areno longer general-purpose processors. It will be appreciated that thedecision to implement a hardware component mechanically, in dedicatedand permanently configured circuitry, or in temporarily configuredcircuitry (e.g., configured by software), may be driven by cost and timeconsiderations. Accordingly, the phrase “hardware component”(or“hardware-implemented component”) should be understood to encompass atangible entity, be that an entity that is physically constructed,permanently configured (e.g., hardwired), or temporarily configured(e.g., programmed) to operate in a certain manner or to perform certainoperations described herein. Considering embodiments in which hardwarecomponents are temporarily configured (e.g., programmed), each of thehardware components need not be configured or instantiated at any oneinstance in time. For example, where a hardware component comprises ageneral-purpose processor configured by software to become aspecial-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware components) at different times. Softwareaccordingly configures a particular processor or processors, forexample, to constitute a particular hardware component at one instanceof time and to constitute a different hardware component at a differentinstance of time. Hardware components can provide information to, andreceive information from, other hardware components. Accordingly, thedescribed hardware components may be regarded as being communicativelycoupled. Where multiple hardware components exist contemporaneously,communications may be achieved through signal transmission (e.g., overappropriate circuits and buses) between or among two or more of thehardware components. In embodiments in which multiple hardwarecomponents are configured or instantiated at different times,communications between such hardware components may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware components have access. Forexample, one hardware component may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware component may then, at alater time, access the memory device to retrieve and process the storedoutput. Hardware components may also initiate communications with inputor output devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein, “processor-implemented component”refers to a hardware component implemented using one or more processors.Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented components. Moreover, the one or more processorsmay also operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an API). The performance ofcertain of the operations may be distributed among the processors, notonly residing within a single machine, but deployed across a number ofmachines. In some example embodiments, the processors orprocessor-implemented components may be located in a single geographiclocation (e.g., within a home environment, an office environment, or aserver farm). In other example embodiments, the processors orprocessor-implemented components may be distributed across a number ofgeographic locations
